Does the esophagus produce digestive enzymes? _____

True or false: the esophagus does not typically carry on absorption of food stuffs. _____

The _____ transports food stuffs to the stomach.

Does the esophagus secrete mucus? _____

Peristaltic waves (mixing waves) generally pass over the stomach every 15-25 seconds, mixing food stuffs with gastric secretions to form _____?

As digestion proceeds, generally vigorous _____ occurs.

Peristalsis forces food stuffs to the _____; but most food stuffs are forced back into the stomach for further mixing.
